Is it a sence to do something like
$dir = realpath(dirname(__FILE__));
// or for php 5.3+:
$dir = realpath(__DIR__)
Or magic constants like DIR and FILE always returns absolute path, so realpath is redundant?
You don't need realpath()
.
The documentation of __FILE__
:
The full path and filename of the file. If used inside an include, the name of the included file is returned. Since PHP 4.0.2,
__FILE__
always contains an absolute path with symlinks resolved whereas in older versions it contained relative path under some circumstances.
So __FILE__
returns an absolute path => realpath()
unnecessary
And if you use __DIR__
:
The directory of the file. If used inside an include, the directory of the included file is returned. This is equivalent to dirname(
__FILE__
). This directory name does not have a trailing slash unless it is the root directory. (Added in PHP 5.3.0.)
__DIR__
also returns an absolute path because dirname()
doesn't cut off the absolute part of the path of __FILE__
=> realpath()
unnecessary
